ASTM D7820 Engine Coolant Corrosion Protection Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM D7820 testing. This test provides an accelerated test method for evaluating engine coolant performance under high temperature oxidizing test conditions of new, used or recycled engine coolants or combinations thereof.

The test method can also serve as a screening tool to determine oxidation stability. The actual service of an engine coolant formulation can only be determined by more extensive bench, dynamometer and field testing.

This test method covers the determination of engine coolant corrosion protection and stability under accelerated thermal and oxidizing conditions using a rotary pressure vessel.

During testing, the engine coolant is subjected to a number of controlled conditions, including temperature and time. Coolant is tested to resist degradation and maintain performance characteristics over time. The test evaluates the coolant's ability to maintain the pH level, prevent corrosion, and prevent the formation of deposits and other types of contaminants.

In general, ASTM D7820 is an important test method in the automotive industry to evaluate the performance of engine coolants and to ensure that they provide adequate protection against corrosion and other types of damage over time.
